Abstract

Wood-inhabiting fungi can decompose wood materials and play a crucial role in the natural world by maintaining the equilibrium of the Earth’s ecosystems. In the present study, five new wood-inhabiting fungal species belonging to the order Hymenochaetales, Hymenochaete weishanensis, Lyomyces albofarinaceus, Lyomyces albomarginatus, Tubulicrinis albobadius and Xylodon musicola, collected from southern China, are proposed based on a combination of morphological features and molecular evidence. Hymenochaete weishanensis is characterized by a coriaceous, tuberculate hymenial surface, a monomitic hyphal system with simple-septate generative hyphae, and ellipsoid to narrow ellipsoid basidiospores (4.0–5.0 × 2.0–3.0 µm); Lyomyces albofarinaceus is characterized by pruinose hymenial surface, a monomitic hyphal system with clamped generative hyphae, and broadly ellipsoid basidiospores (6.0–7.0 × 5.0–6.0 µm); Lyomyces albomarginatus is characterized by the cracked hymenial surface, clamped generative hyphae, and elliposoid basidiospores (4.0–5.5 × 2.7–3.5 µm); Tubulicrinis albobadius is characterized by an arachnoid hymenial surface, a monomitic hyphal system with clamped generative hyphae and cylindrical to allantoid basidiospores (4.0–6.0 × 1.5–2.2 µm) and Xylodon musicola is characterized by an arachnoid hymenial surface, a monomitic hyphal system with clamped generative hyphae and broadly ellipsoid to globe basidiospores (4.0–5.5 × 3.5–5.0 µm). Sequences of the internal transcribed spacers (ITS) and the large subunit (nrLSU) of the nuclear ribosomal DNA (rDNA) markers of the studied samples were generated. Phylogenetic analyses were performed using maximum likelihood, maximum parsimony, and Bayesian inference methods. Full descriptions, illustrations, and phylogenetic analysis results for the five new species are provided.
